Summary Ion-exchange equilibria of metal ions (MnII, CuII, ZnII, CdII and HgII)/H+ systems have been studied at 30, 40, 50 and 60°C on anilinium tin(IV) phosphate (ATP) as a cation exchanger. The exchange isotherms were measured for both forward and reverse reactions with a solution of ionic strength 0.1 by the batch technique. The isotherms are S-shaped for each ion-exchange system. Selectivity coefficients vary linearly with the equivalent fraction $$(\bar X_M )$$ of transition metal ion in the exchanger in the range from 0 to 0.6. The selectivity sequence of ‘zero loading’ is: ZnII 〈MnII〈CuII〈CdII〈HgII. Overall and hypothetical (zero loading) thermodynamic data are evaluated.
